Yes you can do it on the inside. I really wouldn't go any further south of AC on the inside. When in AC get a slip at the Farley Marina and you can get a room at the Golden Nugget. (used to be Trump Marina)
Well the AC trip was a success, good weather and fairly calm waters. Was surprised on how tired I was after 2.25 hrs. of nonstop boating.
Looking at the charts, it seems like Cape May is doable on the inside, @ Capt BOB, why not go any further then south AC
